Without the scope, Ryan can barely make out any details at all along the road. With it, everything is crystal clear.

He can feel the cold ground underneath him starting to warm from his own metabolism as he waits for the convoy to appear. And even then, he has to wait till they reach a certain point before he starts shooting. He also has to make sure the sunlight doesn't shine off his lens and give his position away. Not his first time doing this, no.

Doesn't mean he can't start taking aim now.
